In 1901 Carl Rosenberger and Emanuel Cohn created Coro Inc. in New York City. They initially operated under the name Cohn & Rosenberger until 1943 when they changed the name to Coro, Inc. (CO for Cohn, RO for Rosenberger). The American division of Coro went of business in 1979. The Canadian division produced up until the mid 90's.

During the mid-1940's, Coro introduced their Norseland line of sterling silver jewelry. The designs were inspired by Scandinavian or Danish motifs. This lovely oval brooch depicts a cardinal bird sitting on a branch and surrounded by leaves. The piece measures 1 7/8" across and 2 3/8" in length with safety clasp mechanism. The details are sharp and the brooch has a nice solid weight. Stamped with the image of a viking ship "Norseland by Coro - Sterling - Reg. U.S. Pat. Off." Excellent condition with nice patina.
